What does it mean to remind Guangfa of the large consumption audit of credit cards?

As a reminder, the credit card limit is almost used up, so pay attention to consumption. According to the query of official website of China Guangfa Bank, the reminder of large consumption audit is a daily reminder, telling that the credit card limit is almost used up, so pay attention to consumption. If the large transaction amount exceeds 70% of the total credit card amount, it will automatically remind the large transaction.
